A forum member over amd64notebooks.com web-site has posted a slide presumably from an Advanced Micro Devices’ roadmap concerning the future of the company’s low-power offerings, revealing expansion of AMD’s chips with 25W and 35W power consumption.
64-bit Notebooks Looming
Today’s Mobile Athlon 64 microprocessors for notebooks from AMD are available in two kinds – with 62W and 35W thermal envelope. There are three flavors of powerful chips with 2800+, 3000+ and 3200+ model-numbers functioning at 1.60GHz, 1.80GHz and 2.00GHz respectively. The CPUs have 1MB of full-speed on-die L2 cache and single-channel DDR SDRAM memory controller, like the majority of other AMD Athlon 64 processors in 754-pin packaging. Additionally, AMD has two chips internally named Lancaster with lower power consumption – AMD Mobile Athlon 64 2700+ and AMD Mobile Athlon 64 2800+ – clocked at 1.60GHz with 512KB and 1MB L2 cache.
A number of notebook designers released AMD Mobile Athlon 64-based notebooks, including names like eMachines (Gateway), despite of relatively high consumption of power by the higher-end models.
Mobile AMD Athlon 64 chips with thermal design power at about 62W will continue evolution as expected, but AMD seems to extremely serious about the low-voltage 64-bit processors, according to the leaked roadmap.
Already this quarter AMD is likely to expand its Mobile Athlon 64 lineup with 3000+ and 2800+ models with 512KB of L2 cache as well as 2.0GHz and 1.80GHz clock-speeds respectively. The microprocessors code-named
Additionally, AMD preps a low-power breakthrough this quarter – Mobile Sempron 2800+ and 2600+ with 512KB cache and 25W thermal design power.
Next year the Sunnyvale, California-based chipmaker will offer more powerful 64-bit and 32-bit processors with 25W and 35W thermal envelopes for Socket 754 infrastructure.
Intel’s Pentium M processors specifically tailored for notebooks consume up to 24.5W at 1.70GHz. Intel’s Pentium 4-M processors at 2.40GHz and 2.50GHz typically consume 30W and 35W respectively under maximum load. Mobile Pentium 4 processors that are designed for DTR laptops have TDP of 60W – 94W at clock-speeds from 2.40GHz to 3.20GHz.
AMD said it would start commercial shipments of 90nm offerings in the Q3 2004. However, according to the company’s roadmaps, code-named Odessa CPUs were scheduled for introduction the second half of the year, while the
AMD declined to comment for the report.
